Then go to a different website. Not sure if you noticed but neither Bulbapedia nor Smogon has detailed info about egg moves, tutors, or cross gen move compatibility. If you find a mistake PM him or his staff but I think it's clear that articles about a game released literally 12 hours ago are bound to have the occasional mistake.
Also what are you talking about, Google "Serebii (Pokemon) and click the first link. If it brings you to the wrong generation click the right generation literally at the top of the screen. Serebii is the last place you should bet your life on the accuracy of the info but it's the quickest updated, and most broad in terms of content.
If you know of a website that updates faster and with more general Pokemon info please let me know, I'd be happy to switch.
Also on topic of competitive Pokemon anyone else all hard over Rillaboom getting a 91 base power STAB priority move? It might actually be the strongest priority move in the game. 1% stronger than Talonflame's Brave Bird.
